ArticlesWe are entering 2026, a year in which the world is celebrating another year of innovative digital transformation. However, the IT professionals face an increasingly complex paradox of technologies racing forward at breakneck speed while critical business operations are still running on the decade-old infrastructure. Several industry sectors, like government, healthcare, banking, and manufacturing, are still operating on legacy systems built in the 1970s-1990s.
One of the complex challenges is to run the critical applications and workloads when the legacy hardware has become obsolete. Maintenance of such an environment requires an understanding of both legacy and modern technologies. Studies have revealed that more than 30% of the organization’s technology is built on these monolithic systems. With the decline of skilled experts, it has become necessary for businesses to conduct employee training and learning programs for the legacy systems.
Legacy systems offer reliability and stability. They give familiarity to the business, but can be pretty damaging as time passes by. Conducting employee training programs is not as easy as it seems, as the knowledge gap between legacy and modern technologies continues to widen.
Many skilled legacy veteran engineers are retiring. It means the decades of implicit system knowledge will vanish as they leave the organization. The newly hired professionals are more proficient in modern technologies and often lack the historical context or hands-on experience with legacy code and workflows. With training, businesses can effectively close this gap and ensure operational continuity. In this blog, we will understand the importance of conducting training programs and the need for development for the IT Staff who are working on the emulated legacy infrastructure.
Is Your Legacy Infrastructure Secretly Draining Profits? Transform Your Business with Legacy System Migration.
Here are some reasons why the legacy systems still remain deeply integrated in the infrastructure despite decades of digital transformation:
Legacy systems are known for their reliability and stability, and for their continuous operations over decades. Several industries, like finance, manufacturing, and telecommunication, have continued to rely on legacy systems for their daily operations due to their reliability and comfort with them. The primary reason is, “if it ain’t broke, don’t fix it,” but when a system failure occurs, causing downtime, then it could cost them millions.
Complete legacy system modernization or overhaul can be very expensive and time-consuming. Therefore, organizations prefer to replace damaged parts. But due to legacy hardware obsolescence, the replacement parts have become scarce as they are no longer manufactured. This results in astronomical prices for these scarcely available replacement parts.
Legacy systems have been deeply embedded in the business infrastructure for several decades. It contains large volumes of institutional knowledge, regulatory compliance logic, and accumulated business guides that have been refined over decades. Extracting and translating those large volumes of information into modern systems can be extremely difficult, especially if the original document is missing or corrupted.
There are specific heavy regulations for certain industries. This may be challenging for businesses that want to migrate their legacy systems, as they have previously undergone an extensive certification process. Recertifying the modernized systems with new regulatory systems can be time-consuming and disrupting operations.
Complete replacement or overhauling the legacy infrastructure is a very expensive and time-consuming process. Therefore, many organizations opt for an emulation approach for transforming their business infrastructure.
Here are some of the significant advantages of emulating legacy systems:
With the approaching new year, the IT operations are becoming more complex and integrated. They have become more automated and AI-assisted after being migrated to a modern platform from legacy infrastructure. Yet several businesses’ core infrastructure is designed on legacy operating systems and workloads like HP-UX, OpenVMS, Solaris, and many more. They still rely on legacy codebases.
With time, these legacy systems are becoming obsolete, but the critical applications still continue to operate. They have moved their focus from maintaining the systems to optimizing them, as it will improve the performance, reduce risks, minimize costs, and enable seamless integration with modern technologies like cloud computing, data analytics, and AI.
This results in businesses investing heavily in stabilizing the critical systems on emulated platforms using Stromasys Charon, VMware ESXi, KVM hypervisors, and more. But sustaining them using virtualized and emulated ecosystems requires extensive knowledge of legacy systems and skills to manage modern tech.
That is the reason why IT staff are asked to have an in-depth understanding of:
As modernization of legacy systems accelerates with lightning speed, the knowledge gap also widens as the veteran system experts who have an in-depth understanding are either retiring or have already retired, while the younger professionals are mostly well-versed with modern technologies like DevOps and containers. To meet these demands, businesses need to evolve their development and training sessions beyond traditional upskilling.
Modernize Your Legacy Environment Without Replacing the Entire Infrastructure with Stromasys Charon Solution.
Here are some factors on which organizations need to focus in 2026:
Even today, the legacy operating systems and programs are still considered critical to run operations. But training is no longer limited to educating the employees about simple maintenance, but transforming legacy systems to co-exist with modern tech.
Having a deep understanding of different emulating platforms like Stromasys Charon, VMware ESXi, KVM, and emerging ARM-compatible hypervisors. Training sessions should be conducted to educate the employees on different cross-platform operations, resource optimization, and system performance health in hybrid and distributed setups. Also, creating programs for integration with containerized environments and microservices more effectively.
The threat landscape is increasing day by day. With the evolving threat vectors targeting the outdated systems due to their exposed vulnerabilities. The IT teams should be more skilled and must learn how to integrate advanced security measures while respecting the limitations of legacy applications. They should have a clear understanding of industry regulatory guidelines and compliance. It is recommended to implement zero trust for their legacy environments.
With many organizations now migrating their legacy applications to cloud environments or hybrid systems, the primary focus of the IT training for 2026 should be on emphasizing this infrastructure integration and its characteristics. They should conduct upskilling programs addressing cloud-native monitoring, distributed workload balancing, and cost governance. It is also recommended that teams build a more substantial knowledge of container orchestration tools.
Here are trending upskilling programs that businesses can include in educating their workforce about legacy infrastructure emulation on a modern platform:
Using AI technologies to reshape technical education. It can be used from coding assistants to enterprise-level knowledge continuity tools, automatically preserving institutional expertise and generating explainers for undocumented systems.
Developing the data-driven platforms that are powered by machine learning to curate personalized training roadmaps for IT professionals. These systems can seamlessly assess the existing competencies, job roles, and learning speed to offer targeted modules to the ongoing technical process.
It is suggested to pair experienced legacy system veterans with modern tech specialists. This partnering up will create balance in the team as it will be the collaboration of veteran experts on legacy with skilled professionals working on modern technologies and applications.
Microlearning can be considered the most efficient approach in 2026 for delivering short and informational tutorials directly in workflows. This will ensure IT teams build skills without disrupting workflow.
Effective training involves synchronization with each of the legacy modernization project phases. This includes system assessment and migration to testing and full deployment. It is suggested to use sandbox environments as they help staff to experiment, learn, and innovate in a secure ecosystem.
The transition from 2025 to 2026 isn’t just a calendar shift; it represents the technological leadership test for organizations that have either emulated their legacy systems or are planning to do so.
Its success depends not just on which tools and technologies you are selecting but also on how well-versed your employees are who will be operating and maintaining them. Legacy system modernization is not a simple task but a comprehensive, complex process that should be detail-oriented and AI-informed with multidimensional training programs. This will offer agility to modernize without interruption while training the employees on how to manage their legacy applications during and post-migration for any operational disruptions and security incidents.
